If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy.
We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

Limitless power with virtually no greenhouse gases or radioactive waste. If that sounds too good to be true, that's because it is. For decades, researchers have looked for ways to control, confine and sustain fusion as an energy source. But there has been a lot of progress on a small scale, building on years of physics understanding and progress. Science correspondent Miles O’Brien reports.

(InsideScience) -- The United States, along with 34 other nations, is making a massive investment in time and money to help to build a huge experimental nuclear fusion reactor in the south of France that bills itself as one of the most ambitious energy projects in the world today.
Already more than a decade in the making, critics have questioned its large budget, its ability to keep on schedule and other issues. But proponents say it has the potential to prove out the ability of fusion power plants to provide limitless, clean energy and secure the planet’s future.
Fusion -- it’s how the sun makes energy. And every day, the sun sends out an enormous amount of energy. It radiates more energy each day than the entire Earth uses in one year, and provides more energy in one hour than the entire U.S. can use in a year!
Now imagine if we could re-create even a fraction of that energy using the same process the sun does.
That’s exactly what scientists across the globe plan to do with a mega-project called ITER. It’s a nuclear fusion experiment and engineering effort to bridge the valley toward sustainable, clean, limitless energy-producing fusion power plants of the future.
DennisWhyte of Massachusetts Institute of Technology said, “It’s a very large international collaboration. The United States is part of it. In fact, most of the industrial world is part of this collaboration.
“So right now for instance we expect the very first operations of it in about a decade. And by the latest schedule, the first time it will actually try to get net energy is roughly 20 years away. So ITER is a very exciting experiment, but it’s a little bit frustrating though that it’s taking a while as well too,” said Whyte.
The project officially began in 2006, with an estimated finish date of 2016. Scientists are now aiming for the year 2025 for completion. Researchers acknowledge it’s been an ever-changing journey.
“When we started off, I think, when the agreement was signed, there was still a lot of work to be done on the design and things to be figured out. So, the estimates of time and budget were, you know, not that, not that accurate at that stage. So, the world has been working through all of the issues, and we’ve now closed that out; the design of this machine is, is now finished. Nearly all of the parts have gone out to contract and are now being worked upon,” said Richard Buttery of General Atomics, in San Diego, California.
When it’s finished, the future of energy will be amazing. Unlike fission that happens in a traditional nuclear power plant, where the energy comes from the splitting of heavy atoms, nuclear fusion happens when two lighter atoms come together -- releasing huge amounts of energy. It produces much less waste than even the most advanced nuclear power plants and fossil fuel plants of today -- it’s good, clean energy. But it has its challenges.
“The barriers are largely technological. They are primarily materials. How are the materials going to withstand? We want to make a huge flux of neutron radiation. That’s the whole idea. And we want to create plasmas that are hundreds of millions of degrees hot,” said John Scoville of General Atomics.
Traditional power plants rely mostly on fossil fuels, or water. ITER relies on a tokamak. Inside a tokamak, the energy produced through the fusion of atoms colliding is absorbed as heat in the walls of the tokamak. A fusion power plant will use the heat to produce steam and then electricity (more at...https://www.insidescience.org/video/future-fusion-energy)

I’d like to think we’re smarter than the Sun.
Let’s compare and contrast. Humans, on the one hand, have made enormous advances in science and technology, built cities, cars, computers, and phones. We have split the atom for war and for energy.
What has the Sun done? It’s a massive ball of plasma, made up of mostly hydrogen and helium. It just, kind of, sits there. Every now and then it burps up hydrogen gas into a coronal mass ejection. It’s not a stretch to say that the Sun, and all inanimate material in the Universe, isn’t the sharpest knife in the drawer.
And yet, the Sun has mastered a form of energy that we just can’t seem to wrap our minds around: fusion. It’s really infuriating, seeing the Sun, just sitting there, effortlessly doing something our finest minds have struggled with for half a century.
Why can’t we make fusion work? How long until we can finally catch up technologically with a sphere of ionized gas?
The trick to the Sun’s ability to generate power through nuclear fusion, of course, comes from its enormous mass. The Sun contains 1.989 x 10^30 kilograms of mostly hydrogen and helium, and this mass pushes inward, creating a core heated to 15 million degrees C, with 150 times the density of water.
It’s at this core that the Sun does its work, mashing atoms of hydrogen into helium. This process of fusion is an exothermic reaction, which means that every time a new atom of helium is created, photons in the form of gamma radiation are also released.
The only thing the Sun uses this energy for is light pressure, to counteract the gravity pulling everything inward. Its photons slowly make their way up through the Sun and then they’re released into space. So wasteful.
How can we replicate this on Earth?
Now gathering together a Sun’s mass of hydrogen here on Earth is one option, but it’s really impractical. Where would we put all that hydrogen. The better solution will be to use our technology to simulate the conditions at the core of the Sun.
If we can make a fusion reactor where the temperatures and pressures are high enough for atoms of hydrogen to merge into helium, we can harness those sweet sweet photons of gamma radiation.
The main technology developed to do this is called a tokamak reactor; it’s a based on a Russian acronym for: “toroidal chamber with magnetic coils”, and the first prototypes were created in the 1960s. There are many different reactors in development, but the method is essentially the same.
A vacuum chamber is filled with hydrogen fuel. Then an enormous amount of electricity is run through the chamber, heating up the hydrogen into a plasma state. They might also use lasers and other methods to get the plasma up to 150 to 300 million degrees Celsius (10 to 20 times hotter than the Sun’s core).
Superconducting magnets surround the fusion chamber, containing the plasma and keeping it away from the chamber walls, which would melt otherwise.
Once the temperatures and pressures are high enough, atoms of hydrogen are crushed together into helium just like in the Sun. This releases photons which heat up the plasma, keeping the reaction going without any addition energy input.
Excess heat reaches the chamber walls, and can be extracted to do work.
The challenge has always been that heating up the chamber and constraining the plasma uses up more energy than gets produced in the reactor. We can make fusion work, we just haven’t been able to extract surplus energy from the system… yet.
Compared to other forms of energy production, fusion should be clean and safe. The fuel source is water, and the byproduct is helium (which the world is actually starting to run out of). If there’s a problem with the reactor, it would cool down and the fusion reaction would stop.
The high energy photons released in the fusion reaction will be a problem, however. They’ll stream into the surrounding fusion reactor and make the whole thing radioactive. The fusion chamber will be deadly for about 50 years, but its rapid half-life will make it as radioactive as coal ash after 500 years. Do you know coal ash is radioactive?

Scientists always say that fusion is 20 years away, but this time the physicist says it's for real.

Fusion power

Fusion power is the generation of energy by nuclear fusion. Fusion reactions are high energy reactions in which two lighter atomic nuclei fuse to form a heavier nucleus. When they combine, some of the mass is converted into energy in accordance with the formula . This major area of plasma physics research is concerned with harnessing this reaction as a source of large scale sustainable energy. There is no question of fusion's scientific feasibility, since stellar nucleosynthesis is the process in which stars transmute matter into energy emitted as radiation.

The fusion of two nuclei with lower masses than iron-56 (which, along with nickel-62, has the largest binding energy per nucleon) generally releases energy, while the fusion of nuclei heavier than iron absorbs energy. The opposite is true for the reverse process, nuclear fission. This means that generally only lighter elements are fusable, such as Hydrogen and Helium, and likewise, that generally only heavier elements are fissionable, such as Uranium and Plutonium. There are extreme astrophysical events that can lead to short periods of fusion with heavier nuclei. This is the process that gives rise to nucleosynthesis, the creation of the heavy elements during events such as a supernova.

Lockheed Martin stands as one of the world's premier companies in the aerospace, defense, security, and technologies industry; it is the world's largest defense contractor based on revenue for fiscal year 2014. In 2013, 78% of Lockheed Martin's revenues came from military sales; it topped the list of US federal government contractors and received nearly 10% of the funds paid out by the Pentagon. In 2009 US government contracts accounted for $38.4billion (85%), foreign government contracts $5.8billion (13%), and commercial and other contracts for $900 million (2%).

Scientists always say that fusion is 20 years away, but this time the physicist says it's for real.

FRANCE — Construction on the International Thermonuclear Experimental Reactor (ITER) in southern France has reached the important halfway milestone.
The ITER project consists of 35 nations working on the most complex reactor ever built, consisting of over one million different components, Newsweek reported.
Fusion energy looks to replicate the same process that powers the sun by converting hydrogen atoms into helium through a process that occurs at extreme temperatures, the Guardian reported.
The ITER hopes to use hydrogen fusion controlled by massive superconducting magnets to create heat energy that can drive turbines to produce electricity.
The energy produced would have zero carbon emissions, and could potentially be done at low cost if the production scale is large enough.
The reactor will have to be able to sustain temperatures 150 million degrees celsius — 10 times hotter than the sun's core.
The massive donut-shaped tokamak reactor will be surrounded by giant magnets that take superheated plasma away from the metal walls of the container. This requires the magnets to be cooled to -269 degrees celsius.
The next milestone for the project will be to get to "first plasma" by December 2025 in order to prove the concept is viable.

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.
In a 10-story building the size of three football fields, the Livermore scientists “used 192 lasers to compress a pellet of fuel and generate a reaction in which more energy came out of the fuel core than went into it,” wrote the Washington Post. “Ignition” would mean more energy was produced than was used in the entire process.
"We're closer than anyone's gotten before," said Omar Hurricane, a physicist at Livermore and lead author of the study. "It does show there's promise."
The process ultimately mimics the processes in the core of a star inside the laboratory’s hardware. Nuclear fusion, which is how the sun is heated, creates energy when atomic nuclei fuse and form a larger atom.
"This isn't like building a bridge," Hurricane told USA Today in an interview. "This is an exceedingly hard problem. You're basically trying to produce a star, on a small scale, here on Earth."
A fusion reactor would operate on a common form of hydrogen found in sea water and create minimal nuclear waste while not being nearly as volatile as a traditional nuclear-fission reactor. Fission, used in nuclear power plants, works by splitting atoms.
Hurricane said he does not know how long it will take to reach that point, where fusion is a viable energy source.
"Picture yourself halfway up a mountain, but the mountain is covered in clouds," he told reporters on a conference call Wednesday. “And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’ You just don’t know.”
The beams of the 192 lasers Livermore used can pinpoint extreme amounts of energy in billionth-of-a-second pulses on any target. Hurricane said the energy produced by the process was about twice the amount that was in the fuel of the plastic-capsule target. Though the amount of energy yielded equaled only around 1 percent of energy delivered by the lasers to the capsule to ignite the process.
“When briefly compressed by the laser pulses, the isotopes fused, generating new particles and heating up the fuel further and generating still more nuclear reactions, particles and heat,” wrote the Washington Post, adding that the feedback mechanism is known as “alpha heating.”
DebbieCallahan, co-author of the study, said the capsule had to be compressed 35 times to start the reaction, “akin to compressing a basketball to the size of a pea,” according to USA Today.
While applauding the Livermore team’s findings, fusion experts added researchers have “a factor of about 100 to go.”
"These results are still a long way from ignition, but they represent a significant step forward in fusion research," said Mark Herrmann of the Sandia National Laboratories' Pulsed Power Sciences Center. "Achieving pressures this large, even for vanishingly short times, is no easy task."
Livermore is the site of the multi-billion-dollar National Ignition Facility, funded by the National Nuclear Security Administration. Fusion experiments aren’t the only function of the lab; for example, it also studies the processes of nuclear weapon explosions.
Long-pursued by scientists dating back to Albert Einstein, fusion energy does not emit greenhouse gases or leave behind radioactive waste. Since the 1940s, researchers have employed magnetic fields to contain high-temperature hydrogen fuel. Laser use began in the 1970s.
"We have waited 60 years to get close to controlled fusion," said, Steve Cowley, of the United Kingdom'sCulham Center for Fusion Energy. He added scientists are "now close" with both magnets and lasers. "We must keep at it."
Stewart Prager - director of the Princeton Plasma Physics Laboratory, which studies fusion using magnets - told the Post he was optimistic about fusion energy’s future.

The idea that Fusion will supply energy to the entire world has lingered around for quite some time but can fusion really supply the entire world with energy one day? It has been said about fusion: "It is the energy of the future, and always will be". How close are we to making the dream a reality? Last year, in Germany, a new fusion experiment just began. What are its prospects?
It has been clear since the 1950's that immense amounts of energy can be released by bringing a gas of hydrogen isotopes, deuterium and tritium, to temperatures of 100-200 million degrees. Although this might seem unrealistic, such temperatures have been reached in various experiments around the world. At these temperatures, the gas has become a plasma - the fourth state of matter. There is not much plasma around on Earth, but most of the visible Universe is actually plasma. The challenge in fusion lies in confining a hot, relatively dense plasma efficiently and stably, so that the plasma heat can be sustained by the power generated from the fusion processes in its interior.
Laboratory plasmas created until now have not yet reached the point where the fusion power exceeds the input heating power. However, great progress has been made in performance, as well as in our understanding of the plasma itself. Last year, a new fusion experiment started operation in Greifswald, Germany, the stellarator Wendelstein 7-X. The first results are very encouraging. Within its first two months of operation, plasma temperatures of 100 million degrees were achieved. In this episode, ThomasSunn Pedersen will describe the fundamental principles of fusion energy production, how hot plasmas are confined and describe some of the key achievements and goals of fusion in general, and of the Wendelstein 7-X in particular.

Nuclear Fusion Energy: The Race to Create a Star on Earth

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy.
We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

Limitless power with virtually no greenhouse gases or radioactive waste. If that sounds too good to be true, that's because it is. For decades, researchers have looked for ways to control, confine and sustain fusion as an energy source. But there has been a lot of progress on a small scale, building on years of physics understanding and progress. Science correspondent Miles O’Brien reports.

Nuclear Fusion - MIT Conference - BEST Documentary

Nuclear fusion within reach | Michel Laberge | TEDxKC

This talk was given at a local TEDx event, produced independently of the TED Conferences. Our energy future depends on nuclear fusion, says Michel Laberge. In a lab near Vancouver, Michel and his team are building a prototype fusion reactor that mimics the processes of the sun to produce cheap, clean and abundant energy.
Michel Laberge is a renowned plasma physicist and a pioneer in the research and development of fusion energy. In 2002, he founded General Fusion, which has raised $50 million and currently employs 65 people in Vancouver. The company is viewed as a leader in the pursuit of commercial fusion energy. Dr. Laberge has deep experience in electronics, computers, materials, lithography, optics and fabrication. In his work with General Fusion, he has acquired practical experience...

Scientists always say that fusion is 20 years away, but this time the physicist says it's for real.

FRANCE — Construction on the International Thermonuclear Experimental Reactor (ITER) in southern France has reached the important halfway milestone.
The ITER project consists of 35 nations working on the most complex reactor ever built, consisting of over one million different components, Newsweek reported.
Fusion energy looks to replicate the same process that powers the sun by converting hydrogen atoms into helium through a process that occurs at extreme temperatures, the Guardian reported.
The ITER hopes to use hydrogen fusion controlled by massive superconducting magnets to create heat energy that can drive turbines to produce electricity.
The energy produced would have zero carbon emissions, and could potentially be done at low cost if the production scale is large enough.

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.

Fusion -- it’s how the sun makes energy. And every day, the sun sends out an enormous amount of energy. It radiates more energy each day than the entire Earth uses in one year, and provides more energy in one hour than the entire U.S. can use in a year!
Now imagine if we could re-create even a fraction of that energy using the same process the sun does.
That’s exactly what scientists across the globe plan to do with a mega-project called ITER. It’s a nuclear fusion experiment and engineering effort to bridge the valley toward sustainable, clean, limitless energy-producing fusion power plants of the future.
DennisWhyte of Massachusetts Institute of Technology said, “It’s a very large international collaboration. The United States is part of it. In fact, most of the industrial world is part of this collaboration.
“So right now for instance we expect the very first operations of it in about a decade. And by the latest schedule, the first time it will actually try to get net energy is roughly 20 years away. So ITER is a very exciting experiment, but it’s a little bit frustrating though that it’s taking a while as well too,” said Whyte.
The project officially began in 2006, with an estimated finish date of 2016. Scientists are now aiming for the year 2025 for completion. Researchers acknowledge it’s been an ever-changing journey.
“When we started off, I think, when the agreement was signed, there was still a lot of work to be done on the design and things to be figured out. So, the estimates of time and budget were, you know, not that, not that accurate at that stage. So, the world has been working through all of the issues, and we’ve now closed that out; the design of this machine is, is now finished. Nearly all of the parts have gone out to contract and are now being worked upon,” said Richard Buttery of General Atomics, in San Diego, California.
When it’s finished, the future of energy will be amazing. Unlike fission that happens in a traditional nuclear power plant, where the energy comes from the splitting of heavy atoms, nuclear fusion happens when two lighter atoms come together -- releasing huge amounts of energy. It produces much less waste than even the most advanced nuclear power plants and fossil fuel plants of today -- it’s good, clean energy. But it has its challenges.
“The barriers are largely technological. They are primarily materials. How are the materials going to withstand? We want to make a huge flux of neutron radiation. That’s the whole idea. And we want to create plasmas that are hundreds of millions of degrees hot,” said John Scoville of General Atomics.
Traditional power plants rely mostly on fossil fuels, or water. ITER relies on a tokamak. Inside a tokamak, the energy produced through the fusion of atoms colliding is absorbed as heat in the walls of the tokamak.

What has the Sun done? It’s a massive ball of plasma, made up of mostly hydrogen and helium. It just, kind of, sits there. Every now and then it burps up hydrogen gas into a coronal mass ejection. It’s not a stretch to say that the Sun, and all inanimate material in the Universe, isn’t the sharpest knife in the drawer.
And yet, the Sun has mastered a form of energy that we just can’t seem to wrap our minds around: fusion. It’s really infuriating, seeing the Sun, just sitting there, effortlessly doing something our finest minds have struggled with for half a century.
Why can’t we make fusion work? How long until we can finally catch up technologically with a sphere of ionized gas?
The trick to the Sun’s ability to generate power through nuclear fusion, of course, comes from its enormous mass. The Sun contains 1.989 x 10^30 kilograms of mostly hydrogen and helium, and this mass pushes inward, creating a core heated to 15 million degrees C, with 150 times the density of water.
It’s at this core that the Sun does its work, mashing atoms of hydrogen into helium. This process of fusion is an exothermic reaction, which means that every time a new atom of helium is created, photons in the form of gamma radiation are also released.
The only thing the Sun uses this energy for is light pressure, to counteract the gravity pulling everything inward. Its photons slowly make their way up through the Sun and then they’re released into space. So wasteful.
How can we replicate this on Earth?
Now gathering together a Sun’s mass of hydrogen here on Earth is one option, but it’s really impractical. Where would we put all that hydrogen. The better solution will be to use our technology to simulate the conditions at the core of the Sun.
If we can make a fusion reactor where the temperatures and pressures are high enough for atoms of hydrogen to merge into helium, we can harness those sweet sweet photons of gamma radiation.
The main technology developed to do this is called a tokamak reactor; it’s a based on a Russian acronym for: “toroidal chamber with magnetic coils”, and the first prototypes were created in the 1960s. There are many different reactors in development, but the method is essentially the same.
A vacuum chamber is filled with hydrogen fuel. Then an enormous amount of electricity is run through the chamber, heating up the hydrogen into a plasma state. They might also use lasers and other methods to get the plasma up to 150 to 300 million degrees Celsius (10 to 20 times hotter than the Sun’s core).
Superconducting magnets surround the fusion chamber, containing the plasma and keeping it away from the chamber walls, which would melt otherwise.
Once the temperatures and pressures are high enough, atoms of hydrogen are crushed together into helium just like in the Sun. This releases photons which heat up the plasma, keeping the reaction going without any addition energy input.
Excess heat reaches the chamber walls, and can be extracted to do work.
The challenge has always been that heating up the chamber and constraining the plasma uses up more energy than gets produced in the reactor. We can make fusion work, we just haven’t been able to extract surplus energy from the system… yet.
Compared to other forms of energy production, fusion should be clean and safe. The fuel source is water, and the byproduct is helium (which the world is actually starting to run out of). If there’s a problem with the reactor, it would cool down and the fusion reaction would stop.
The high energy photons released in the fusion reaction will be a problem, however. They’ll stream into the surrounding fusion reactor and make the whole thing radioactive. The fusion chamber will be deadly for about 50 years, but its rapid half-life will make it as radioactive as coal ash after 500 years. Do you know coal ash is radioactive?

The Sun uses its enormous mass to crush hydrogen into fusion, releasing enormous energy. How long will it be until we’ve got this energy source for Earth?

This talk was given at a local TEDx event, produced independently of the TED Conferences. Our energy future depends on nuclear fusion, says Michel Laberge. In a lab near Vancouver, Michel and his team are building a prototype fusion reactor that mimics the processes of the sun to produce cheap, clean and abundant energy.
Michel Laberge is a renowned plasma physicist and a pioneer in the research and development of fusion energy. In 2002, he founded General Fusion, which has raised $50 million and currently employs 65 people in Vancouver. The company is viewed as a leader in the pursuit of commercial fusion energy. Dr. Laberge has deep experience in electronics, computers, materials, lithography, optics and fabrication. In his work with General Fusion, he has acquired practical experience in plasma physics and with all modern plasma diagnostic techniques.
Since 2002 Dr. Laberge has been working on the General Fusion project. He has written numerous scientific papers, has been awarded 10 patents, and has nine more pending.

FRANCE — Construction on the International Thermonuclear Experimental Reactor (ITER) in southern France has reached the important halfway milestone.
The ITER project consists of 35 nations working on the most complex reactor ever built, consisting of over one million different components, Newsweek reported.
Fusion energy looks to replicate the same process that powers the sun by converting hydrogen atoms into helium through a process that occurs at extreme temperatures, the Guardian reported.
The ITER hopes to use hydrogen fusion controlled by massive superconducting magnets to create heat energy that can drive turbines to produce electricity.
The energy produced would have zero carbon emissions, and could potentially be done at low cost if the production scale is large enough.
The reactor will have to be able to sustain temperatures 150 million degrees celsius — 10 times hotter than the sun's core.
The massive donut-shaped tokamak reactor will be surrounded by giant magnets that take superheated plasma away from the metal walls of the container. This requires the magnets to be cooled to -269 degrees celsius.
The next milestone for the project will be to get to "first plasma" by December 2025 in order to prove the concept is viable.

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.
In a 10-story building the size of three football fields, the Livermore scientists “used 192 lasers to compress a pellet of fuel and generate a reaction in which more energy came out of the fuel core than went into it,” wrote the Washington Post. “Ignition” would mean more energy was produced than was used in the entire process.
"We're closer than anyone's gotten before," said Omar Hurricane, a physicist at Livermore and lead author of the study. "It does show there's promise."
The process ultimately mimics the processes in the core of a star inside the laboratory’s hardware. Nuclear fusion, which is how the sun is heated, creates energy when atomic nuclei fuse and form a larger atom.
"This isn't like building a bridge," Hurricane told USA Today in an interview. "This is an exceedingly hard problem. You're basically trying to produce a star, on a small scale, here on Earth."
A fusion reactor would operate on a common form of hydrogen found in sea water and create minimal nuclear waste while not being nearly as volatile as a traditional nuclear-fission reactor. Fission, used in nuclear power plants, works by splitting atoms.
Hurricane said he does not know how long it will take to reach that point, where fusion is a viable energy source.
"Picture yourself halfway up a mountain, but the mountain is covered in clouds," he told reporters on a conference call Wednesday. “And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’ You just don’t know.”
The beams of the 192 lasers Livermore used can pinpoint extreme amounts of energy in billionth-of-a-second pulses on any target. Hurricane said the energy produced by the process was about twice the amount that was in the fuel of the plastic-capsule target. Though the amount of energy yielded equaled only around 1 percent of energy delivered by the lasers to the capsule to ignite the process.
“When briefly compressed by the laser pulses, the isotopes fused, generating new particles and heating up the fuel further and generating still more nuclear reactions, particles and heat,” wrote the Washington Post, adding that the feedback mechanism is known as “alpha heating.”
DebbieCallahan, co-author of the study, said the capsule had to be compressed 35 times to start the reaction, “akin to compressing a basketball to the size of a pea,” according to USA Today.
While applauding the Livermore team’s findings, fusion experts added researchers have “a factor of about 100 to go.”
"These results are still a long way from ignition, but they represent a significant step forward in fusion research," said Mark Herrmann of the Sandia National Laboratories' Pulsed Power Sciences Center. "Achieving pressures this large, even for vanishingly short times, is no easy task."
Livermore is the site of the multi-billion-dollar National Ignition Facility, funded by the National Nuclear Security Administration. Fusion experiments aren’t the only function of the lab; for example, it also studies the processes of nuclear weapon explosions.
Long-pursued by scientists dating back to Albert Einstein, fusion energy does not emit greenhouse gases or leave behind radioactive waste. Since the 1940s, researchers have employed magnetic fields to contain high-temperature hydrogen fuel. Laser use began in the 1970s.
"We have waited 60 years to get close to controlled fusion," said, Steve Cowley, of the United Kingdom'sCulham Center for Fusion Energy. He added scientists are "now close" with both magnets and lasers. "We must keep at it."
Stewart Prager - director of the Princeton Plasma Physics Laboratory, which studies fusion using magnets - told the Post he was optimistic about fusion energy’s future.

The idea that Fusion will supply energy to the entire world has lingered around for quite some time but can fusion really supply the entire world with energy one day? It has been said about fusion: "It is the energy of the future, and always will be". How close are we to making the dream a reality? Last year, in Germany, a new fusion experiment just began. What are its prospects?
It has been clear since the 1950's that immense amounts of energy can be released by bringing a gas of hydrogen isotopes, deuterium and tritium, to temperatures of 100-200 million degrees. Although this might seem unrealistic, such temperatures have been reached in various experiments around the world. At these temperatures, the gas has become a plasma - the fourth state of matter. There is not much plasma around on Earth, but most of the visible Universe is actually plasma. The challenge in fusion lies in confining a hot, relatively dense plasma efficiently and stably, so that the plasma heat can be sustained by the power generated from the fusion processes in its interior.
Laboratory plasmas created until now have not yet reached the point where the fusion power exceeds the input heating power. However, great progress has been made in performance, as well as in our understanding of the plasma itself. Last year, a new fusion experiment started operation in Greifswald, Germany, the stellarator Wendelstein 7-X. The first results are very encouraging. Within its first two months of operation, plasma temperatures of 100 million degrees were achieved. In this episode, ThomasSunn Pedersen will describe the fundamental principles of fusion energy production, how hot plasmas are confined and describe some of the key achievements and goals of fusion in general, and of the Wendelstein 7-X in particular.

America and The Nuclear Fusion Full Documentary 2016 Movies

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.
In a 10-story building the size of three football fields, the Livermore scientists “used 192 lasers to compress a pellet of fuel and generate a reaction in which more energy came out of the fuel core than went into it,” wrote the Washington Post. “Ignition” would mean more energy was prod...

Breakthrough in Nuclear Fusion? - Prof. Dennis Whyte

Nuclear fusion is the holy grail of energy generation because by fusing two hydrogen atoms together into a single helium atom it releases enormous amounts of energy, yet represents a clean, safe, sustainable and secure form of power.
The most tried and true approach for generating nuclear fusion energy has been a tokamak fusion reactor, which uses very high density magnetic fields to compress and contain a plasma to 100 million degrees. But none has been able to generate more electricity than it consumes. Until now.
DirectorWhyte will describe the ARC nuclear fusion reactor (shown above right), based on a new superconducting material, for achieving very high density magnetic fields. It will be used as a research center, but could ultimately become a prototype for an inexpensive 200MW...

World's First NUCLEAR SALT REACTOR - Documentary Films

World's First NUCLEAR SALT REACTOR - Documentary Films
A liquified salt activator (MSR) is a class of nuclear fission activators where the primary coolant, or also the energy itself, is a liquified salt mix. MSRs perform at higher temperature levels than water-cooled reactors for greater thermodynamic savings, while staying at low vapor tension.
In many designs the nuclear energy is dissolved in the molten fluoride salt coolant as uranium tetrafluoride (UF4). Solid energy designs rely on ceramic energy dispersed in a graphite matrix, regarding the molten salt providing low stress, high temperature level air conditioning.
The early Aircraft Reactor Experiment (1954) was primarily motivated by the tiny dimension that the style might offer, while the Molten-Salt Reactor Experiment (1965-- ...

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.
In a 10-story building the size of three football fields, the Livermore scientists “used 192 lasers to compress a pellet of fuel and generate a reaction in which more energy came out of the fuel core than went into it,” wrote the Washington Post. “Ignition” would mean more energy was produced than was used in the entire process.
"We're closer than anyone's gotten before," said Omar Hurricane, a physicist at Livermore and lead author of the study. "It does show there's promise."
The process ultimately mimics the processes in the core of a star inside the laboratory’s hardware. Nuclear fusion, which is how the sun is heated, creates energy when atomic nuclei fuse and form a larger atom.
"This isn't like building a bridge," Hurricane told USA Today in an interview. "This is an exceedingly hard problem. You're basically trying to produce a star, on a small scale, here on Earth."
A fusion reactor would operate on a common form of hydrogen found in sea water and create minimal nuclear waste while not being nearly as volatile as a traditional nuclear-fission reactor. Fission, used in nuclear power plants, works by splitting atoms.
Hurricane said he does not know how long it will take to reach that point, where fusion is a viable energy source.
"Picture yourself halfway up a mountain, but the mountain is covered in clouds," he told reporters on a conference call Wednesday. “And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’ You just don’t know.”
The beams of the 192 lasers Livermore used can pinpoint extreme amounts of energy in billionth-of-a-second pulses on any target. Hurricane said the energy produced by the process was about twice the amount that was in the fuel of the plastic-capsule target. Though the amount of energy yielded equaled only around 1 percent of energy delivered by the lasers to the capsule to ignite the process.
“When briefly compressed by the laser pulses, the isotopes fused, generating new particles and heating up the fuel further and generating still more nuclear reactions, particles and heat,” wrote the Washington Post, adding that the feedback mechanism is known as “alpha heating.”
DebbieCallahan, co-author of the study, said the capsule had to be compressed 35 times to start the reaction, “akin to compressing a basketball to the size of a pea,” according to USA Today.
While applauding the Livermore team’s findings, fusion experts added researchers have “a factor of about 100 to go.”
"These results are still a long way from ignition, but they represent a significant step forward in fusion research," said Mark Herrmann of the Sandia National Laboratories' Pulsed Power Sciences Center. "Achieving pressures this large, even for vanishingly short times, is no easy task."
Livermore is the site of the multi-billion-dollar National Ignition Facility, funded by the National Nuclear Security Administration. Fusion experiments aren’t the only function of the lab; for example, it also studies the processes of nuclear weapon explosions.
Long-pursued by scientists dating back to Albert Einstein, fusion energy does not emit greenhouse gases or leave behind radioactive waste. Since the 1940s, researchers have employed magnetic fields to contain high-temperature hydrogen fuel. Laser use began in the 1970s.
"We have waited 60 years to get close to controlled fusion," said, Steve Cowley, of the United Kingdom'sCulham Center for Fusion Energy. He added scientists are "now close" with both magnets and lasers. "We must keep at it."
Stewart Prager - director of the Princeton Plasma Physics Laboratory, which studies fusion using magnets - told the Post he was optimistic about fusion energy’s future.

Nuclear fusion is the holy grail of energy generation because by fusing two hydrogen atoms together into a single helium atom it releases enormous amounts of energy, yet represents a clean, safe, sustainable and secure form of power.
The most tried and true approach for generating nuclear fusion energy has been a tokamak fusion reactor, which uses very high density magnetic fields to compress and contain a plasma to 100 million degrees. But none has been able to generate more electricity than it consumes. Until now.
DirectorWhyte will describe the ARC nuclear fusion reactor (shown above right), based on a new superconducting material, for achieving very high density magnetic fields. It will be used as a research center, but could ultimately become a prototype for an inexpensive 200MW power plant, vaulting nuclear fusion from scientific curiosity to potential commercialization.
The ARC reactor is being designed to produce at least 3 times the power required to run it, which has never been done before and is the result of several new technologies which dramatically reduce the size and cost.
The biggest breakthrough is a new superconducting material which produces a much higher magnetic field density, yielding a ten-fold increase in fusion power per volume. Molten salt will be used as a liquid cooling blanket for fast heat transfer and easy maintenance. And 3D printing techniques will allow the fabrication of reactor components in shapes that cannot be made by milling machines. The result is a much smaller, lower cost and highly efficient modular power plant with zero emissions and abundant fuel.
Dennis Whyte, recently promoted to run MIT’s Nuclear Science and Engineering Department and Director of MIT’s PlasmaScience & Fusion Center, works in magnetic fusion and specializes in the interface between the plasma and materials.
Dennis received his PhD from the Universite du Quebec in 1993. A Fellow of the American Physical Society, Dennis was awarded the Department of Energy’s Plasma PhysicsJunior Faculty Award in 2003 and won the International Atomic Energy Agency’s Nuclear Fusion Prize in 2013. He is a two-time winner of the MIT Joel and RuthSpira Award for teaching excellence. Among his many lectures on fusion energy research, Dennis was an invited speaker at CERAWeek and the National Science Foundation’s Engineering Distinguished Lecturer in 2015.

Professor Miklos Porkolab is an internationally recognized physicist, known for his work in both experimental and theoretical plasma physics. Since 1995 he has been the Director of MIT's PlasmaScience and Fusion Center (PSFC) and the Head of the PSFC Physics ResearchDivision. He graduated from the University of British Columbia (BASc in Engineering Physics, 1963) and obtained his Ph.D. in Applied Physics at Stanford University in 1967. While at Princeton University in the early 1970s, Porkolab carried out pioneering experimental and theoretical research in the area of nonlinear wave-wave and wave-particle interactions and parametric instabilities. His current research interests include advanced tokamak physics research through heating and current profile control with RF waves, and a study of turbulence and transport in tokamaks. Porkolab is a fellow of the American Physical Society and the American Association for the Advancement of Science.
Nuclear fusion is the source of energy that powers the stars in the universe. It is a nuclear reaction of light nuclei (isotopes of hydrogen) fusing into heavier ones (helium) once they collide with sufficiently high speeds to overcome the repulsive Coulomb forces of like charged particles. This releases enormous amounts of energy through the conversion of mass (0.7 % of the original mass) into energy. In practice to achieve such a high temperature "plasma furnace" while maintaining its burn for long time durations has been an extremely challenging scientific and technological problem. The most promising approach is the so-called tokamak concept. Such a device consists of a toroidally shaped vacuum chamber, surrounded by magnetic coils and the plasma is initiated by inducing an electric current in the plasma which also creates its own magnetic field that helps to confine the plasma. I will review the enormous scientific and technical progress made in the last few decades in fusion research, its present status, including the building of a multi-billion dollar scale burning plasma experiment (ITER) as an international activity, and finally will discuss some of the technical challenges that remain toward realizing a demonstration fusion power plant.

Nuclear Fusion Energy: The Race to Create a Star on Earth

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy.
We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

Is alluring but elusive fusion energy possible in our lifetime?

Limitless power with virtually no greenhouse gases or radioactive waste. If that sounds too good to be true, that's because it is. For decades, researchers have looked for ways to control, confine and sustain fusion as an energy source. But there has been a lot of progress on a small scale, building on years of physics understanding and progress. Science correspondent Miles O’Brien reports.

The Future of Fusion Energy Part 1 of 5

(InsideScience) -- The United States, along with 34 other nations, is making a massive investment in time and money to help to build a huge experimental nuclear fusion reactor in the south of France that bills itself as one of the most ambitious energy projects in the world today.
Already more than a decade in the making, critics have questioned its large budget, its ability to keep on schedule and other issues. But proponents say it has the potential to prove out the ability of fusion power plants to provide limitless, clean energy and secure the planet’s future.
Fusion -- it’s how the sun makes energy. And every day, the sun sends out an enormous amount of energy. It radiates more energy each day than the entire Earth uses in one year, and provides more energy in one hour than the entire U.S. can use in a year!
Now imagine if we could re-create even a fraction of that energy using the same process the sun does.
That’s exactly what scientists across the globe plan to do with a mega-project called ITER. It’s a nuclear fusion experiment and engineering effort to bridge the valley toward sustainable, clean, limitless energy-producing fusion power plants of the future.
DennisWhyte of Massachusetts Institute of Technology said, “It’s a very large international collaboration. The United States is part of it. In fact, most of the industrial world is part of this collaboration.
“So right now for instance we expect the very first operations of it in about a decade. And by the latest schedule, the first time it will actually try to get net energy is roughly 20 years away. So ITER is a very exciting experiment, but it’s a little bit frustrating though that it’s taking a while as well too,” said Whyte.
The project officially began in 2006, with an estimated finish date of 2016. Scientists are now aiming for the year 2025 for completion. Researchers acknowledge it’s been an ever-changing journey.
“When we started off, I think, when the agreement was signed, there was still a lot of work to be done on the design and things to be figured out. So, the estimates of time and budget were, you know, not that, not that accurate at that stage. So, the world has been working through all of the issues, and we’ve now closed that out; the design of this machine is, is now finished. Nearly all of the parts have gone out to contract and are now being worked upon,” said Richard Buttery of General Atomics, in San Diego, California.
When it’s finished, the future of energy will be amazing. Unlike fission that happens in a traditional nuclear power plant, where the energy comes from the splitting of heavy atoms, nuclear fusion happens when two lighter atoms come together -- releasing huge amounts of energy. It produces much less waste than even the most advanced nuclear power plants and fossil fuel plants of today -- it’s good, clean energy. But it has its challenges.
“The barriers are largely technological. They are primarily materials. How are the materials going to withstand? We want to make a huge flux of neutron radiation. That’s the whole idea. And we want to create plasmas that are hundreds of millions of degrees hot,” said John Scoville of General Atomics.
Traditional power plants rely mostly on fossil fuels, or water. ITER relies on a tokamak. Inside a tokamak, the energy produced through the fusion of atoms colliding is absorbed as heat in the walls of the tokamak. A fusion power plant will use the heat to produce steam and then electricity (more at...https://www.insidescience.org/video/future-fusion-energy)

How Far Away is Fusion? Unlocking the Power of the Sun

The Sun uses its enormous mass to crush hydrogen into fusion, releasing enormous energy. How long will it be until we’ve got this energy source for Earth?

I’d like to think we’re smarter than the Sun.
Let’s compare and contrast. Humans, on the one hand, have made enormous advances in science and technology, built cities, cars, computers, and phones. We have split the atom for war and for energy.
What has the Sun done? It’s a massive ball of plasma, made up of mostly hydrogen and helium. It just, kind of, sits there. Every now and then it burps up hydrogen gas into a coronal mass ejection. It’s not a stretch to say that the Sun, and all inanimate material in the Universe, isn’t the sharpest knife in the drawer.
And yet, the Sun has mastered a form of energy that we just can’t seem to wrap our minds around: fusion. It’s really infuriating, seeing the Sun, just sitting there, effortlessly doing something our finest minds have struggled with for half a century.
Why can’t we make fusion work? How long until we can finally catch up technologically with a sphere of ionized gas?
The trick to the Sun’s ability to generate power through nuclear fusion, of course, comes from its enormous mass. The Sun contains 1.989 x 10^30 kilograms of mostly hydrogen and helium, and this mass pushes inward, creating a core heated to 15 million degrees C, with 150 times the density of water.
It’s at this core that the Sun does its work, mashing atoms of hydrogen into helium. This process of fusion is an exothermic reaction, which means that every time a new atom of helium is created, photons in the form of gamma radiation are also released.
The only thing the Sun uses this energy for is light pressure, to counteract the gravity pulling everything inward. Its photons slowly make their way up through the Sun and then they’re released into space. So wasteful.
How can we replicate this on Earth?
Now gathering together a Sun’s mass of hydrogen here on Earth is one option, but it’s really impractical. Where would we put all that hydrogen. The better solution will be to use our technology to simulate the conditions at the core of the Sun.
If we can make a fusion reactor where the temperatures and pressures are high enough for atoms of hydrogen to merge into helium, we can harness those sweet sweet photons of gamma radiation.
The main technology developed to do this is called a tokamak reactor; it’s a based on a Russian acronym for: “toroidal chamber with magnetic coils”, and the first prototypes were created in the 1960s. There are many different reactors in development, but the method is essentially the same.
A vacuum chamber is filled with hydrogen fuel. Then an enormous amount of electricity is run through the chamber, heating up the hydrogen into a plasma state. They might also use lasers and other methods to get the plasma up to 150 to 300 million degrees Celsius (10 to 20 times hotter than the Sun’s core).
Superconducting magnets surround the fusion chamber, containing the plasma and keeping it away from the chamber walls, which would melt otherwise.
Once the temperatures and pressures are high enough, atoms of hydrogen are crushed together into helium just like in the Sun. This releases photons which heat up the plasma, keeping the reaction going without any addition energy input.
Excess heat reaches the chamber walls, and can be extracted to do work.
The challenge has always been that heating up the chamber and constraining the plasma uses up more energy than gets produced in the reactor. We can make fusion work, we just haven’t been able to extract surplus energy from the system… yet.
Compared to other forms of energy production, fusion should be clean and safe. The fuel source is water, and the byproduct is helium (which the world is actually starting to run out of). If there’s a problem with the reactor, it would cool down and the fusion reaction would stop.
The high energy photons released in the fusion reaction will be a problem, however. They’ll stream into the surrounding fusion reactor and make the whole thing radioactive. The fusion chamber will be deadly for about 50 years, but its rapid half-life will make it as radioactive as coal ash after 500 years. Do you know coal ash is radioactive?

Nuclear fusion within reach | Michel Laberge | TEDxKC

This talk was given at a local TEDx event, produced independently of the TED Conferences. Our energy future depends on nuclear fusion, says Michel Laberge. In a lab near Vancouver, Michel and his team are building a prototype fusion reactor that mimics the processes of the sun to produce cheap, clean and abundant energy.
Michel Laberge is a renowned plasma physicist and a pioneer in the research and development of fusion energy. In 2002, he founded General Fusion, which has raised $50 million and currently employs 65 people in Vancouver. The company is viewed as a leader in the pursuit of commercial fusion energy. Dr. Laberge has deep experience in electronics, computers, materials, lithography, optics and fabrication. In his work with General Fusion, he has acquired practical experience in plasma physics and with all modern plasma diagnostic techniques.
Since 2002 Dr. Laberge has been working on the General Fusion project. He has written numerous scientific papers, has been awarded 10 patents, and has nine more pending.
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

FRANCE — Construction on the International Thermonuclear Experimental Reactor (ITER) in southern France has reached the important halfway milestone.
The ITER project consists of 35 nations working on the most complex reactor ever built, consisting of over one million different components, Newsweek reported.
Fusion energy looks to replicate the same process that powers the sun by converting hydrogen atoms into helium through a process that occurs at extreme temperatures, the Guardian reported.
The ITER hopes to use hydrogen fusion controlled by massive superconducting magnets to create heat energy that can drive turbines to produce electricity.
The energy produced would have zero carbon emissions, and could potentially be done at low cost if the production scale is large enough.
The reactor will have to be able to sustain temperatures 150 million degrees celsius — 10 times hotter than the sun's core.
The massive donut-shaped tokamak reactor will be surrounded by giant magnets that take superheated plasma away from the metal walls of the container. This requires the magnets to be cooled to -269 degrees celsius.
The next milestone for the project will be to get to "first plasma" by December 2025 in order to prove the concept is viable.

America and The Nuclear Fusion Full Documentary 2016 Movies

A team of scientists in California announced Wednesday they are one step closer to developing the almost mythical pollution-free, controlled fusion-energy reaction, though the goal of full “ignition” is still far off.
Researchers at the federally-funded Lawrence Livermore National Laboratory revealed in a study released Wednesday in the peer-reviewed journal Nature that, for the first time, one of their experiments has yielded more energy out of fusion than was used in the fuel that created the reaction.
In a 10-story building the size of three football fields, the Livermore scientists “used 192 lasers to compress a pellet of fuel and generate a reaction in which more energy came out of the fuel core than went into it,” wrote the Washington Post. “Ignition” would mean more energy was produced than was used in the entire process.
"We're closer than anyone's gotten before," said Omar Hurricane, a physicist at Livermore and lead author of the study. "It does show there's promise."
The process ultimately mimics the processes in the core of a star inside the laboratory’s hardware. Nuclear fusion, which is how the sun is heated, creates energy when atomic nuclei fuse and form a larger atom.
"This isn't like building a bridge," Hurricane told USA Today in an interview. "This is an exceedingly hard problem. You're basically trying to produce a star, on a small scale, here on Earth."
A fusion reactor would operate on a common form of hydrogen found in sea water and create minimal nuclear waste while not being nearly as volatile as a traditional nuclear-fission reactor. Fission, used in nuclear power plants, works by splitting atoms.
Hurricane said he does not know how long it will take to reach that point, where fusion is a viable energy source.
"Picture yourself halfway up a mountain, but the mountain is covered in clouds," he told reporters on a conference call Wednesday. “And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’ You just don’t know.”
The beams of the 192 lasers Livermore used can pinpoint extreme amounts of energy in billionth-of-a-second pulses on any target. Hurricane said the energy produced by the process was about twice the amount that was in the fuel of the plastic-capsule target. Though the amount of energy yielded equaled only around 1 percent of energy delivered by the lasers to the capsule to ignite the process.
“When briefly compressed by the laser pulses, the isotopes fused, generating new particles and heating up the fuel further and generating still more nuclear reactions, particles and heat,” wrote the Washington Post, adding that the feedback mechanism is known as “alpha heating.”
DebbieCallahan, co-author of the study, said the capsule had to be compressed 35 times to start the reaction, “akin to compressing a basketball to the size of a pea,” according to USA Today.
While applauding the Livermore team’s findings, fusion experts added researchers have “a factor of about 100 to go.”
"These results are still a long way from ignition, but they represent a significant step forward in fusion research," said Mark Herrmann of the Sandia National Laboratories' Pulsed Power Sciences Center. "Achieving pressures this large, even for vanishingly short times, is no easy task."
Livermore is the site of the multi-billion-dollar National Ignition Facility, funded by the National Nuclear Security Administration. Fusion experiments aren’t the only function of the lab; for example, it also studies the processes of nuclear weapon explosions.
Long-pursued by scientists dating back to Albert Einstein, fusion energy does not emit greenhouse gases or leave behind radioactive waste. Since the 1940s, researchers have employed magnetic fields to contain high-temperature hydrogen fuel. Laser use began in the 1970s.
"We have waited 60 years to get close to controlled fusion," said, Steve Cowley, of the United Kingdom'sCulham Center for Fusion Energy. He added scientists are "now close" with both magnets and lasers. "We must keep at it."
Stewart Prager - director of the Princeton Plasma Physics Laboratory, which studies fusion using magnets - told the Post he was optimistic about fusion energy’s future.

The idea that Fusion will supply energy to the entire world has lingered around for quite some time but can fusion really supply the entire world with energy one day? It has been said about fusion: "It is the energy of the future, and always will be". How close are we to making the dream a reality? Last year, in Germany, a new fusion experiment just began. What are its prospects?
It has been clear since the 1950's that immense amounts of energy can be released by bringing a gas of hydrogen isotopes, deuterium and tritium, to temperatures of 100-200 million degrees. Although this might seem unrealistic, such temperatures have been reached in various experiments around the world. At these temperatures, the gas has become a plasma - the fourth state of matter. There is not much plasma around on Earth, but most of the visible Universe is actually plasma. The challenge in fusion lies in confining a hot, relatively dense plasma efficiently and stably, so that the plasma heat can be sustained by the power generated from the fusion processes in its interior.
Laboratory plasmas created until now have not yet reached the point where the fusion power exceeds the input heating power. However, great progress has been made in performance, as well as in our understanding of the plasma itself. Last year, a new fusion experiment started operation in Greifswald, Germany, the stellarator Wendelstein 7-X. The first results are very encouraging. Within its first two months of operation, plasma temperatures of 100 million degrees were achieved. In this episode, ThomasSunn Pedersen will describe the fundamental principles of fusion energy production, how hot plasmas are confined and describe some of the key achievements and goals of fusion in general, and of the Wendelstein 7-X in particular.

Breakthrough in Nuclear Fusion? - Prof. Dennis Whyte

Nuclear fusion is the holy grail of energy generation because by fusing two hydrogen atoms together into a single helium atom it releases enormous amounts of energy, yet represents a clean, safe, sustainable and secure form of power.
The most tried and true approach for generating nuclear fusion energy has been a tokamak fusion reactor, which uses very high density magnetic fields to compress and contain a plasma to 100 million degrees. But none has been able to generate more electricity than it consumes. Until now.
DirectorWhyte will describe the ARC nuclear fusion reactor (shown above right), based on a new superconducting material, for achieving very high density magnetic fields. It will be used as a research center, but could ultimately become a prototype for an inexpensive 200MW power plant, vaulting nuclear fusion from scientific curiosity to potential commercialization.
The ARC reactor is being designed to produce at least 3 times the power required to run it, which has never been done before and is the result of several new technologies which dramatically reduce the size and cost.
The biggest breakthrough is a new superconducting material which produces a much higher magnetic field density, yielding a ten-fold increase in fusion power per volume. Molten salt will be used as a liquid cooling blanket for fast heat transfer and easy maintenance. And 3D printing techniques will allow the fabrication of reactor components in shapes that cannot be made by milling machines. The result is a much smaller, lower cost and highly efficient modular power plant with zero emissions and abundant fuel.
Dennis Whyte, recently promoted to run MIT’s Nuclear Science and Engineering Department and Director of MIT’s PlasmaScience & Fusion Center, works in magnetic fusion and specializes in the interface between the plasma and materials.
Dennis received his PhD from the Universite du Quebec in 1993. A Fellow of the American Physical Society, Dennis was awarded the Department of Energy’s Plasma PhysicsJunior Faculty Award in 2003 and won the International Atomic Energy Agency’s Nuclear Fusion Prize in 2013. He is a two-time winner of the MIT Joel and RuthSpira Award for teaching excellence. Among his many lectures on fusion energy research, Dennis was an invited speaker at CERAWeek and the National Science Foundation’s Engineering Distinguished Lecturer in 2015.
